The pentafluorophenyl-substituted diphosphine (C₆F₅)PhPCH₂CH₂PPh(C₆F₅) has been prepared, as a 1:1.7 mixture of rac (1a) and meso (1b) isomers, in four steps from dppe. The reaction between [Cp*RhCl(μ-Cl)]2 and 1 in the ...

Herbivorous and deposit-feeding gastropods are a major component of archaeological shell middens worldwide. They provide a wealth of information about subsistence, economy, environment, and climate, but are generally ...

The sterically crowded title compound, C₁₄H₁₂O₄, crystallizes as centrosymmetric hydrogen-bonded dimers involving the carboxyl groups. The naphthoquinone ring system is folded by 11.5 (1)° about a vector joining the 1,4-C ...

2-Ferrocenyl-substituted pyrylium salts are produced when orthomanganated chalcones are reacted with ethynylferrocene in CCl4. When the reaction is carried out in benzene, intermediate ferrocenyl-substituted (η5-pyranyl)Mn(CO)3 ...

In this, the 2002 Banks Memorial Lecture, I have two main aims. First, I will trace what has been discovered by botanists about the Mt Taranaki/Egmont flora since Joseph Banks scanned the mountain from the deck of Cook’s ...

A survey of the Australasian clinical medical physics and biomedical engineering workforce was carried out in 2009 following on from a similar survey in 2006. 621 positions (equivalent to 575 equivalent full time (EFT) ...

A survey of the medical physics and biomedical engineering workforce in Australia and New Zealand was carried out in 2012 following on from similar surveys in 2009 and 2006. 761 positions (equivalent to 736 equivalent full ...

We report new archaeological excavations from northern Australia revealing part of a charcoal design likely to be c. 28,000 years old (and chrono-stratigraphically constrained within the period 15,600-45,600 cal BP) on a ...

A new alkaloid, 5-bromo-8-methoxy-1-methyl-β-carboline (1), has been isolated from the New Zealand marine bryozoan Pterocella vesiculosa. Structural elucidation was achieved through NMR spectroscopic and mass spectrometric ...

The title compound, [Mn(C₁₀H₉O₃)(CO)₄], is formed by orthomanganation of 3'-acetoxyacetophenone at the sterically crowded ortho site. The atoms of the benzene and the cyclometallated rings are coplanar to within <0.018 Å, ...

The ceramic utensils used for eating and drinking such as plates, cups, bowls and other items have been a fundamental part of many societies since ancient times. The word “ceramics” is itself derived from the Greek word ...

Although claims are often made that Australia has evidence of some of the oldest rock art in the world and features prominently in rock art studies globally, very little of it is securely dated. Recently the first Pleistocene ...

With the International Technology Roadmap for Semiconductors predicting below-25nm feature-size VLSIs, powered by DC power supplies of less than 1V, protection against transients has become mandatory for modern electronic ...

The McMurdo Dry Valleys collectively comprise the most extensive ice-free region in Antarctica and are considered one of the coldest arid environments on Earth. In low-altitude maritime-associated valleys, mineral soil ...

The strength of mid-southern latitude westerly atmospheric circulation plays an important role in global climate. Due to a lack of long, continuous, high-resolution paleoclimate archives from mid-southern latitudes, it ...

Vibrational spectra of vapor-phase dimethylamine (DMA) and pyrrole have been recorded in the 1000 to 13000 cm–1 region using long path conventional spectroscopy techniques. We have focused on the absolute intensities of ...

To investigate relationships between epibenthic macrofauna and bathyal habitat characteristics, we examined the abundance, diversity and community composition of amphipod crustaceans relative to environmental variables on ...
